Tire tread



FIG. 1 is a perspective view of a tire tread showing my new design, it being understood that the pattern is repeated uniformly throughout the circumference of the tread;

FIG. 2 is a front elevational view thereof; a top plan view thereof is identical to the front elevational view; and a bottom plan view thereof is identical to the front elevational view;

FIG. 3 is a rear elevational view thereof;

FIG. 4 is a left side view thereof; and a right side view thereof is a mirror image of the left side view; and,

FIG. 5 is an enlarged fragmentary view of the upper 5-5 to lower 5-5 in FIG. 2.

The broken lines illustrate environmental subject matter only and form no part of the claimed design. The dash-dot-dash broken lines define the boundary of the tire tread and form no part of the claimed design. Surface shading lines in the drawings depict the character or contour of the surfaces represented and are not themselves separate elements of said design. Stippling in the drawings depicts the character of the surfaces represented and is not a separate element of said design. 

CLAIM The ornamental design for a tire tread, as shown and described.
